Description

Technical Field

[0001] This utility model belongs to the field of suction cup technology, and in particular relates to a rotating suction cup. Background Technology

[0002] In existing technologies, suction cups, as commonly used adsorption tools, are widely used in various fields such as industrial production and household products. Traditional suction cups typically require manual expulsion of air after being placed against the mounting surface. This process is cumbersome, especially when the mounting surface is uneven. Manual expulsion makes it difficult to ensure complete air removal, leading to unstable adsorption force. This not only wastes time and manpower but also results in inconsistent air expulsion, making it difficult to create a proper negative pressure space between the suction cup and the mounting surface. This can easily lead to weak adhesion and affect the normal use of the suction cup. Utility Model Content

[0003] In view of the above-mentioned defects in the prior art, the purpose of this utility model is to provide a rotating suction cup, which aims to solve the problems of the existing suction cup requiring manual air expulsion after adhering to the mounting surface, which is cumbersome and has unstable adsorption effect, and to achieve simultaneous adsorption and air expulsion with a single press.

[0004] To achieve the above objectives, this utility model provides a rotating suction cup, including an adsorption sheet and an elastic pad. The adsorption sheet includes an adsorption surface and a force-receiving surface. The adsorption surface is adapted to adhere to the mounting surface. The elastic pad is disposed on one side of the force-receiving surface. The elastic pad is adapted to drive the adsorption sheet to maintain a flat state. The elastic pad is adapted to transmit pressure to the adsorption sheet to drive the air out between the adsorption surface and the mounting surface.

[0005] Preferably, the elastic pad is configured to continuously apply a pre-tightening force to the adsorption sheet when the suction cup is not in operation, so that the adsorption surface remains in a stress-free and naturally flat state.

[0006] Preferably, the elastic pad is in the shape of a disc that is suitable for completely covering the force-bearing surface, which can achieve full force application on the adsorption sheet and ensure that the air between the adsorption surface and the mounting surface can be completely discharged with a single press.

[0007] Preferably, the rotating suction cup further includes a suction cup support, and the elastic pad is disposed between the suction plate and the suction cup support.

[0008] Preferably, the suction cup holder includes a disc portion adapted to apply pressure to the elastic pad and a cantilever extending from the disc portion, the cantilever being adapted to mount a hook, or the cantilever being adapted to directly suspend an item.

[0009] Preferably, the disc portion includes several coaxially arranged annular ribs and several radial ribs evenly radiating from the center of the disc portion. The annular ribs are suitable for constraining the deformation range of the elastic gasket and maintaining edge sealing. The radial ribs extend to the outer periphery of the disc portion. The radial ribs and the annular ribs are staggered to form a mesh-like load-bearing surface, ensuring uniform pressure distribution, dispersing the suspension load, and improving the deformation resistance of the suction cup bracket.

[0010] Preferably, the radial rib has a plurality of stepped portions at one end near the center of the disc portion, and each stepped portion has a transition fillet at its corner.

[0011] Preferably, the rotary suction cup further includes a rotary drive unit and a transmission column. A mounting base is provided in the center of the force-bearing surface. One end of the transmission column is mounted on the mounting base, and the other end of the transmission column is adapted to pass through the elastic pad and the suction cup and is threadedly engaged with the rotary drive unit.

[0012] Preferably, the resilient gasket includes a clearance hole that allows the mounting base to be exposed.

[0013] Preferably, the elastic pad is attached to the force-bearing surface, or the suction plate and the rotary drive unit adjust the distance between them through the transmission column, and clamp and limit the elastic pad and the suction cup bracket.

[0014] The beneficial effects of this utility model are:

[0015] By incorporating elastic gaskets, the slight bending that may occur in the adsorption sheet when not under stress due to material properties or storage and transportation is eliminated, ensuring that the adsorption surface remains flat and guaranteeing seamless contact between the adsorption surface and the mounting surface during initial bonding. The elastic gaskets flatten the adsorption sheet while also evenly distributing pressure, ensuring uniform force across the entire surface. This drives air between the adsorption surface and the mounting surface to be expelled synchronously from the edges, avoiding the "air pocket" phenomenon caused by uneven local pressure during traditional manual compression and eliminating dead zones for air release.

[0016] In summary, because the elastic pad continuously provides flattening force, users only need to press once to completely flatten the adsorption sheet onto the mounting surface, simultaneously expelling air. There is no need to repeatedly adjust the pressing position, significantly improving the ease of operation. Attached Figure Description

[0025] like Figure 1-4 A rotary suction cup includes, from top to bottom, a rotary drive unit 1, a suction cup bracket 2, an elastic pad 3, and an adsorption plate 4, and further includes a transmission column 5 adapted to connect the adsorption plate 4 and the rotary drive unit 1. The adsorption plate 4 includes an adsorption surface 41 and a force-bearing surface 42, the adsorption surface 41 being adapted to conform to a mounting surface. A mounting base 421 is disposed at the center of the force-bearing surface 42. The elastic pad 3 is disposed on one side of the force-bearing surface 42, and includes a clearance hole 31 that allows the mounting base 421 to be exposed. One end of the transmission column 5 is mounted to the mounting base 421, and the other end of the transmission column 5 is adapted to pass through the elastic pad and the suction cup, and is threadedly engaged with the rotary drive unit 1. The elastic pad 3 is configured to continuously apply a pre-tightening force to the adsorption plate 4 when the suction cup is not in operation, keeping the adsorption surface 41 in a stress-free, naturally flat state. The elastic pad 3 is in the shape of a circular disc adapted to completely cover the force-bearing surface 42, enabling full force application to the adsorption plate 4 and ensuring that air between the adsorption surface 41 and the mounting surface is completely expelled with a single press.

[0026] In this embodiment, the suction cup bracket 2 includes a disc portion 21 adapted to apply pressure to the elastic gasket 3 and a cantilever 22 extending from the disc portion 21. The cantilever 22 is adapted to install a hook. The disc portion 21 includes several coaxially arranged annular ribs 212 and several radial ribs 211 evenly arranged from the center of the disc portion 21. The annular ribs 212 are adapted to constrain the deformation range of the elastic gasket 3 and maintain edge sealing. The radial ribs 211 extend to the outer periphery of the disc portion 21. The radial ribs 211 and the annular ribs 212 are staggered to form a mesh-like load-bearing surface, ensuring uniform pressure distribution, dispersing the suspension load, and improving the deformation resistance of the suction cup bracket 2. Several stepped portions 2111 are formed at one end of the radial ribs near the center of the disc portion 21. The stepped portions 2111 are adapted to provide deformation space for the adsorption sheet 4. A transition rounded corner is provided at the corner of each stepped portion 2111.

[0027] In this embodiment, the elastic pad 3 is adhered to the force-bearing surface 42. In some other embodiments, the suction plate 4 and the rotary drive unit 1 are adjusted in distance via the transmission column 5, and the elastic pad 3 and suction cup bracket 2 are clamped and positioned.

[0028] The working principle of the rotary suction cup is as follows: The adsorption surface 41 of the adsorption plate 4 is attached to the mounting surface, the elastic gasket 3 covers the force-bearing surface 42, and the disc portion 21 of the suction cup bracket 2 is pressed against the outside of the elastic gasket 3. When force is applied to the suction cup bracket 2 or the rotary drive unit 1, the elastic gasket 3 undergoes elastic deformation under pressure, uniformly transmitting pressure to the adsorption plate 4, causing the air between the adsorption surface 41 and the mounting surface to be discharged from the edge. When the rotary drive unit 1 is threadedly engaged with the transmission column 5, the transmission column 5 moves upward, causing the central force-bearing surface 42 of the adsorption plate 4 to deform and bulge upward, forming a sealed negative pressure space between the adsorption surface 41 and the mounting surface. Driving the rotary drive unit 1 to rotate in the other direction, the transmission column 5 drives the adsorption plate 4 to return to its original position, and the rebound force of the elastic gasket 3 causes air to enter between the adsorption surface 41 and the mounting surface, the negative pressure disappears, and the suction cup can be easily removed.

[0029] The above embodiments are only used to illustrate the technical solutions of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this utility model without departing from the spirit and scope of the technical solutions of this utility model.
